Answer:
e. None of the above assumptions would invalidate the model
Step-by-step explanation:
Incomplete question "The constant growth model is given below: P0 = [D0(1 + g)]/[(rs - g)]"
According to dividend discount model,
P0 = D1/(R-G)
D1 - Dividend at t =1
R - Required rate
G - Growth rate
This would be invalid if R < G. In other words, Dividend growth model will be invalid in only one situation, that is, when growth rate is more than require return. In this situation growth model cannot be used.
